Title: Information recording and reproducing device
Inventor: SAGA YOSHIHIRO
IPC: G11B7/09
Filed: 1994-09-12
Abstract: PURPOSE: To eliminate data errors of a writing and a reproducing by impressing a focusing offset voltage with which reproducing beams are focused to a focusing servo means at the time of reproducing information and eliminating focus displacements. focus displacements. CONSTITUTION: A switch 114 provided in an offset adding means 106 is closed by being informed that a device is in a reproducing operation from a system part 110. Then, a preliminarily set offset voltage is impressed on an focusing loop.

IPC: B21D28/00
Filed: 1986-09-16
Abstract: PURPOSE:To prevent the generation of force bending an external lead when burr is pushed and crushed, and to obviate the curving of the external lead by placing the external lead in the direction opposite to the surface of a pushing press in a cutting bending process and bending burr generated on the processing of the external lead in a semiconductor device.

When a tie bar cutting edge 6 is pushed down and a tie bar section 3 is cut, burr 7 can be formed on the surface side of the package 1. A cutting bending process is started under the state. The surface of the package 1 is directed upward in the direction of the package 1 placed at that time. When a lead bending punch 11 is lowered and an external lead is pressed under the state and the external lead 2 is intended to be bent, burr 7 is broken, but force applied to a lead bending mold 9 for the external lead 2 is applied over the whole region of the base at that time, and force intending to curve the external lead 2 in the horizontal direction is not generated. Accordingly, the external lead 2 is not bent in the direction rectangular to the direction of force of a press.
